226 ANNUAL REPORT OF THE Off. Doc. 



Pure water has boon haviiiji^ its sliarc of attention. ^^> now 

 know that on every farm, as well as in every town home, there is 

 danger of water pollution. Happily, there is a Aery cheap and 

 effective remedy. The most primitive, as well as effective, is by 

 boiling. But as few resort to this method for cattle, it has been 

 ascertained that if water is allowed to pass through comparatively 

 clean gravel, and then through coarse and fine sand — the whole 

 mass about three feet thick — the upper part to be scraped off 

 to the depth of only half an inch every two months — the animals 

 drinking the water thus purified will be in better condition in evoi'y 

 way, and bring a higher price than when allowed to drink the im- 

 pure water of most of our farms. Many of our good, old-fashioned 

 farmer friends may not see the importance of this, but the time is 

 not far off when the miry barnyard and the impure water of the 

 barn and many of the fields will have to go.
